np'rnr snow-now AND snowsman'nn;

- To all whom may concern; f

Be it known that I, f-WALTEB Lnsmn STADIG, a citizen of the United States of America, and resident of the town of St. Francis, in the Stateof Maine, in the United States of America, have invented certain new and useful Improvements in Rotary Snow-Blows and Snow-Loaders, of whic the following is the specification,

'The invention relates to improvements in snow plows and snow loaders as described in the present specificationandillustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel arrangement and construction of parts, whereby the snow is rapidly removed from the roadway and conveyed to one side thereof or loaded on to other vehicles to be carted away later.

I The objects of the invention are to econ'o "mize in the matter of expenses incidental to the employment of numerous men to clear the roadways and other surfaces in cities, towns or other places from the accumulations of snow and ice following the storms and snow falls during the winter time, to improve the operation and constructive features of the various parts included in the snow'plow, patented inUnited States under Nos. 1,084,498 and 1,093,493 on Jan-, uary 13th, 1914, and April 14th, 1914, respectively and to add'parts to and change some of the arrangements in. the said patented invention in order to facilitate the removal of snow. to enable the attendants .of the machine to work into side .snowbanks without placing the motive or draft power into the deeper snows to insure the delivery of the snow raised from the roadway into receptacles or suitable piles, to 'de both front andrear sled or trucks wit; precision so that the cutters may always reach the most advantageous position. for engaging with the snow or ice, to increase the speed in the elevation and delivery of the snow and generally to provide a machine that is efficient, durable, and 'coi'nparativelyinex pensive to construct. i i

In the drawings, Figure I is'a side elevation of the machine. a

Fig. 2 is a side elevation showing various parts" removed to disclose mechanism not shown in Fig. 1. S t

ranged for draft power such as horses,

though any power may be used for propelling purposes and said sleds may be in the form of wheel trucks :and driven ac cordingly or the machine may be hauled a motor driven vehicle, however the set over device illustrated'is for a horse drawn machine and for another power changes would necessarily be made.

In the form of the lnvention described the tongue 4 is slidably mounted on the rail 5 at the front of the sled 2, said tongue beingi firmly secured in the sleeve 6. The reel is pivotally mounted on the sleeve 6 and the cable 8 arranged to wind-thereon,

the ends of said cable being secured at each side of the-sled 2, Said cable having a sufiicient number of turns "onthe reel 7 to 1 adjustthe tongue on the rail 5 and thereby permit the machine to travel in one path and the horses in another, which is very useful in clearing away banks of'snow at the side of a'road.

The reel is turned by the hand wheel 9 and the tongue moved to thefdesired position. I r I The rear sled 3 isprovided with a ring 10 serving'as a turntable, said turntable on one-side having the rack 11 in arc-shape, similar to a segmental gear.

. The upper half 12 of. the ring orturntable is rigidly secured to the frame 13," the latter being flexibly connected to the main frame 1 as customary and as more fully described in my earlier patent 'hereinbefor'e referred to.

The upper ring'12 forms the bearing on which the lower ring 10'turns, when the sled 3 is independently guided'toward the side or center of a road as the case may be.

The hand wheel 14 is operated in turning,

the rear sled 3 and this wheel is mounted on r suspenslon bars,

18 coacting with the rack 11 in turning the ring 10 and consequently in swinging the sled 3.

The driving gear shaft 20 is journaled in suitable bearings supported'by the frame 25 and are adjustably secured to the plates I 26 inone or other ofthe vertical slots 26", said plates being straight vertical sections of the plow frame 27. The said plow frame 27 projects upwardly and intermediate of its height the .eyebolt 77 is secured thereto, the eye-78 being on the inner side. The reach rod 79 having-the ring ends 80 and the turnbuckle center 81 is secured at one end to the eye 78 and at the other to the ring bolt82 secured to the frameof the machine, thus providing further adjustment for the plowframe 27. r

The upper ends ofthe bars 25 are pivotally secured to the cranks 28 fixedly mounted on the shaft 29.

. The segmental gear 30- is .fixedly mounted on the'shaft 29 and coacts with the worm 31 operated bythe rotation of the shaft 32 controlled by the hand Wheel 33, said shaft 32 'beingjournaled in the bearings 34 and 35. It Wlll now be seen that by turning the hand Wheel the worm coacting with said segmental gear will operate said gear and consequentlythe cranks, thereby raising or lowerin the said beams through'thesaid The bearings 36 are supported at the lower ends of the beams 22 and in these bearings the cutter shaft 37 is journaled. a

The cutters 38 are fixedly mounted on the shaft 37 at each side of the machineand are formed of the vanes 39 of, considerable length transversely of the machine and in cross section of spider shape, the vanes of one cutter being set-centrally in relation to a the vanes of the other cutter so as to keep one always in contact with the road. V

.- The vanes 39 reach fout from their hub 40inan easy curve and at the end portions 41' are recessed for the knives 42,Tthe latter being bent intothe sharpened shoe ends 43 to more readily cut the snow and ice. The knives are secured to the vanes byflthe bolts 44and nuts 45. l a f i ;-The central space between the cutters 3 8 isoccupied by the V- low-46 which isfor'a ward inthree incline sections 47', 48 and 49, the central section terminating in the fiat stru't"54 which is secured to'the aforesaid plow frame that supports theplow The cutters 38 are rotated with'the shaft 37 and the'l'atter is driven by the chain 155 and sprockets 56 and 57, the latter being vmounted on the shaft 37 and the former on the aforesaid gear shaft driven by the motor. This driving mechanism turns the said cutters severalhundreds of revolutions per minute, which has the effect o'fdriving great" quantities offlsnow upwardly and "for, that reason the. inclose d chutes 58 are provided,- said chutes terminating in flaring and substantially semi-circular delivery hoods 59 re inforced by the heavy plates60, that extend .The bar51 is reinforced at each side'by the Q beyond the hoods at each end andformbaf' 1.1

fies to protect the machineryfrom the flying snow and also form rigid supportsfor other parts of the mechanism} It is desirable to control the which swirls up the chute and by centrifugal force flies off the edgero'f the hood ingreat clouds, and in. order to direct this cloud of flying snow the deflector plates '61 and 62 are provided the; inner plates61'being pivot ally securedto the plates 60.and extending for the-complete breadth of thesaid hoods and at eachend terminating the downf; wardly hangingflanges 63; The outer plates 62 alsoextendthe complete'breadth of'the said hoods-and terminate-theflanges 64, said outer plates 62 being pivotally joined to; the innerplates61; vr.

The brackets 65stand froin the backs ofthe inner plates 61, and the brackets 66 stand out" from the backs v of. the -outer plates 62.

brackets 65. The levers 67 are provided with spring j pawls 70 engaging in toothed quadrants 71 as-customaryl-in such devices.

The outer "plates 62 areoperatediby the cables 72 and chains 73, said cables being-secured to the brackets 66jand extending under the pulleys 74, said chains passingthrough the rings 75 and locking in theslots 76'beneath said rings.

. The levers-67 are for operating'theinner; plates and these levers'turn ashaft 68 on which the cranks 69 are fixedly. mounted; said cranks being pivotally connected to the r ,In operating thesedeflecting "plates i said levers 67 are moved .until' the inner plates assume the desired angle, say slightly above the horizontal, and the said chains and cables are pulled or let out, until; the outer plates assume the; desired angle, say forming obtuse angles with saidinner plates, this will insure the deposit of the flying snow beyond the machine at each side thereof.

In the operation of the invention the machine is drawn along the road to be cleared and the cutters set in motion. The plow in V-form with its chisel cutters cuts the packed snow and directs all the snow in its path into the paths of the cutters which are also work Various changes may be madein the construction of this machine and in its mode of operation without departing from the spirit of the invention so long as they are within the scope of the claims for novelty following.

WVhat I claim is 1. In a snow plow, a frame supportedon suitable running gear, a cutter chamber, a plow supported from said frame, a rotary cutter supported and driven from said frame and situated to the rear of said plow, and a semi-circular hood extending from the rear wall of said chamber and terminating above said plow.
